适用于

  • ONTAP 9
  • 存储效率
  • 压缩
  • 温度敏感型存储效率(TSSE)

回答

温度敏感型存储效率 (TSSE) 是 ONTAP 9 中执行Auto Adaptive Compression的初始方法,在 ONTAP 9.8 中引入,ONTAP 可以根据块温度决定以较轻的 8k 或更强的 32k 压缩组压缩数据。

追加信息

  • 参考卷与聚合压缩(指的是与 TSSE/CBSE 一起使用的逻辑重复数据删除)
  • 9.11.1 之前的 TSSE 的负面影响是在 ONTAP 9.8 或更高版本的卷级别和聚合级别没有压缩(报告 0)节省
  • 参考顺序打包 9.13.1
  • 参考活动数据顺序重新打包 9.14.1,其中温度不再重要
  • 参考 QAT 和 Pensando 平台,以及ONTAP 9 中有哪些不同的压缩算法及其使用场景
  • 参考重新打包选项和问题根源,可能存在额外的 KB
  • 参考自 9.12.1 起可通过 volume effi inactive 在 set advanced 下使用的阈值调整
